Project title: Design, Simulation and Prototyping of a Variable Intake System for the Yamaha WR 250F

Project Overview

The project consisted of designing, simulating, and prototyping a variable intake airbox for the Yamaha WR/YZ 250F. The new airbox design was based on a Ricardo Wave engine model, designed with SolidWorks, and simulated with CFD. An intake length scientific model was built using Microsoft Excel, combining the results acquired as well with real engine performance the optimum trumpet lengths were finalized. The variable intake system actuation system was precisely designed developing a gear and servo position calculator based on the intake length scientific model previously developed. The airbox was finally prototyped by 3D printing.
